Ok on kernel boot up I got
*Kernel command line: root=/dev/ram rw console=ttyS1,115200*
That means it didn't changed

As per your saying I did following things
=> setenv console ttyS0
=> savenv
Saving Environment to Flash...
Un-Protected 1 sectors
Erasing Flash...
. done
Erased 1 sectors
Writing to Flash... done
Protected 1 sectors

then reboot & kernel boot up

             You need set u-boot environment variable "console" to "ttyS0"
             In u-boot command line execute
             setenv console ttyS0
             then
             saveenv
             end reboot board
             Hope this help.

                    Is this question is after seeing this line

        Then command
                 prompt

                 In /etc/intab it was
                 ::respawn:/sbin/getty -L ttS0 115200 VT100  //orginal
        setting
                 I changed to

                 /command prompt is not visible it get stuck here
                 *console handover: boot [udbg0] -> real [ttyS1*]_

                 My MPC8xxx uses ttyS0 and I am pretty it's external DB9
        is not
                 connected and jumpered to an internal header (by default).

                      ttyS1 is an odd tty for the console.  Are you sure
        you are
                 connected
                      to ttyS1? Are you sure ttyS1 is brought out to the
        external
                 connector,
                      if there one?

                      My MPC8xxx uses ttyS0 and I am pretty it's
        external DB9 is not
                      connected and jumpered to an internal header (by
        default).
